On Halloween night, ABC started off with Scared Shrekless which did alright but may have been competing with Trick or Treating. At 8:30pm, a 90 minute episode of Dancing with the Stars was down nine tenths in viewers and four tenths in the demo for a series low in the demo despite not airing in the lower HUT 8:00 half hour. This was a somewhat disappointing performance but Halloween could have played a factor. At 10pm, Castle was up a strong 1.8 million viewers and three tenths in the demo despite the lower lead-in. The total viewer count is the best since the season premiere.

Over on CBS, the demos took a hit which could have been partly attributed to Halloween. At 8pm, How I Met Your Mother was up seven tenths in viewers but down a tenth in the demo with a Halloween episode. At 8:30pm, 2 Broke Girls was down two tenths in viewers and two tenths in the demo as it continues to be fall's hottest new comedy. At 9pm, Two and a Half Men took a big hit as it was down 1.4 million viewers and eight tenths in the demo for a season low. Last week, it looked like it had stabilized at a great number but this week was another big fall. Now it is performing where it was at this point last year which is still not bad at all after all the turmoil. At 9:30pm, Mike & Molly followed suit but not as much as it was down seven tenths in viewers and half a demo point for a season low. At 10pm, Hawaii Five-0 was down a tenth in viewers and the demo, once again winning the demo for the hour.

NBC just can't get anything right on Monday nights. At 8pm, The Sing Off was up two tenths in viewers but down a tenth in the demo for another season low. I thought this show might be at least on the map against Dancing with the Stars, but it's not. The momentum this show was building in Decembers has evaporated. At 10pm, the series premiere of newsmagazine Rock Center with Brian Williams did absolutely nothing, debuting well below The Playboy Club's series premiere numbers. After these numbers and the Prime Suspect repeat numbers, Playboy isn't looking all that bad. NBC will probably let this ride out until Smash premieres in February though.
Finally on FOX, Terra Nova started off and was down 1.7 million viewers and seven tenths in the demo from its last airing two weeks ago. It hit a series low and while they might try to attribute it to Halloween, something tells me this show is beginning a slide that will probably spell its end after the 13 episode season is over. At 9pm, House was down 1.6 million viewers and six tenths in the demo, hitting a series low. It is time for this long running medical drama to call it quits after this season.
